A spokesman for Massachusetts General Hospital says the British singer underwent vocal cord microsurgery to stop recurrent bleeding from a benign polyp. The condition is usually the result of unstable blood vessels in the vocal cord that can rupture.

The hospital says the 23-year-old Grammy winner came to Boston to undergo the surgery with Dr. Steven Zeitels, director of the Massachusetts General Hospital Voice Center. The hospital says Zeitels expects Adele to make a full recovery from the laser microsurgery.
